Boluwaji hi. The cost will vary, depending if you do the website yourself (in case you have the knowledge and time), buy a template or hire a programmer (hundreds to thousands of dollars). Generally people may pay for templates a few hundreds of dollars, but be aware you need to have time and desire to learn because you will face technical challenges. Search in internet for a proper model for you that includes technical assistance. Have success.
